RECEPTCLE.

Application med August 13, 1921.

To all whom. t 'may conce/m.'

Be it known that I, Vieron DURAND, Jr., a citizen of the United States, and a resident of Vineland. in the county of Cumberland, State of New Jersey, have invented certa-in new and useful Improvements in Receptacles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to receptacles in which the inner container for the liquids or other substances is separated by a'vacuum from an enclosing medium. Devices having these general characteristics are sometimes called thermos bottles which also embody metal covers.

Among the objects of my 'invention is to provide an improved receptacle such as a. vacuum or thermos bottle, which is made substantially entirely of glass or other suitable material; which is provided With means minimizing the possibilities of breakage;

` which can be readily cleaned both exteriorly and interiorly; which may be produced cheaply; a receptacle provided with an insu'- lating vacuum in which the disadvantage of having the liquid or a portion of it pass into the space between the metal cover and the glass casing as frequently happens in the devices now in use is avoided, the metal cover. being dispensed with in my invention.

Other objects of my invention will appear in the f-apecification andclaims below.

Referring to the drawings forming a part of the specification and in which the same vreference characters are used throughout the views to designate the same parts, I have illustrated some embodiments oi my invention; Figure 1 is a vertical sectional view, part, however, being in elevation, showing the construction of a thermos bottle containingr my invention;

Fig. 2 is a horizontal section through the bottle taken on the line 2-2 of Fig. 1;

Fig. 3 is a modified form of my invention, the same being shown substantially in vertical crow-section, but with parts in ele- 'vation; and

Fig. 4 is a horizontal sectional view taken on the line 4-4 of Fig. 3.

Serial No. 491,915.

Referring first to Fig. 1, the bottle therein shown embodying my invention consists of a heavy outer casing 1 of glass or other suitable material, the main or body portion 2 of which is substantially cylindrical, and havinga shoulder 3 and a neck 4. The lower part 5 of the glass outer casing 1, is preferably substantially spherical. bottle is also provided with a thin inner member or inner container 6 of glass or othervsuita-ble material, the walls of which are thin and the shape of this inner container substantiallyv'hconforms to that of the outer casing. en the bottle is completed a space 7 is provided between the inner container 6 and the outer casing 1 throughout their entire extent except at the mouth of the bottle where they are rigidly integrall connected together.

The said ln ma 'ng the vacuum bottle, the wouterv casing is first made of substantially the same shape as that shown in Fig. 1 except that the body portion 2 is `continuously cylindrical and is open throughout its entire diameter at the lower end thereof. The inner container or thin glass 'bottle 6 is formed by blowing in substantially the same shape as that shown in Fig. l and is then inserted through the large open bottom end of the casing 1 and the top of its neck or mouth is then fused to the inside of the neck or mouth 4.- of the casing 1. After these -have been joined, the open end of the casing 1 is then reheated and drawn or blown or shaped into substantially spherical form, as shown in Fig. 1. An exhaust opening is, of course, left at the tip 8 of thecasing and before the air is exhausted from between the casing 1 and the inner container 6, .he surfaces may be silvered in any ordinary and well known manner. Then the air 1s exhausted from between the parts 1 and 6 and when thoroughly exhausted, the tip. 8 is sealed.

lt should be noted that I preferably provide the outer casing 1 vwith a series of projections 9 forming between the inner container and the casing of the bottle recesses 10. In these recesses, spherical spheres, or balls of cork, rubber, or any other suitable yielding material may be forced before the end 5 of the outer container is closed. These cork or rubber balls 11 serve to steady and maintain the thin narrow bottle or container 6 within the outer casing and to prevent the neck of the inner container 6 from being broken when the bottle, as a whole, is subjected to a sudden shock, as, for instance, by dropping the bottle upon the floor. v

Adjacent the lower spherical end 5 of the outer container, I preferably therein provide a rim or ring 12 and integral with the body of the outer container, and up to and against the shoulder formed by the said ring 12, I press or form or otherwise provide the upper parts of the spherical end 5 with screw threads 13 preferably formed in the glass itself. This provides a means for fastening a metal bottom 14 to the bottom of the outer glass casing 1. This bottom 14 is preferably cylindrical on its sides and is flat on its bottom, and may contain any suitable yielding material 15, such as cork, rubber or asbestos to bear against the outer spherical surface lof the glass end 5. Preferably, this material 15 is provided with a hole or opening within which the tip 8 may be seated and kept out of contact with the metal.

I lalso preferably provide another ring or rim 16 adjacent the top of the outer-casing or cover 1, and against the shoulder thereby formed and above the rim 16 I also press into the glass screw threads 17 over which may be threaded the threaded end 18 of a drinkingcup 19 to be screwed down against said shoulder or ring 16 which also protects the neck 4 of the bottle when the same is beingtransported.

etwe'en the rings or rims 12 and 16, I

.preferably provide the outer surface of the glass container or casing 1 with corrugations. In ligure 1, these corrugations ,are shown as vertical and they form a rel- 'atlvely roughened surface which may be readily grasped and bv means of which the bottle may br ecurely held in the hand without fear ot i, .ppingz These ribs also serve to strengthen the outer glass cover or casing 1. Y

In Figs. 3 and 4, I have shown a modified form ofl my invention. In this modified form, the screw threads 17 are located on the neck of the bottle near the mouth of it;

" thatvis to say, near the upper end of the outer container, and the cup 19 is smaller than that shown in Fig. 1 and tits more- -closely around the top of the bottle.-

this form or construction, it is veryeasy'to provide the interior of the outer casing 1 with a relatively roughened surface be- 'tween the horizontal corrugations so that 'it be retained in thatposition by the horizon-- tal corrugations on the inside of the outer casino 1. f n

It 1s, of course, understood that the bottle may be provided with a stopper 20 of the ordinary construction and that any number of balls or small masses of springy material 1l may be suit-ably inserted between the two glass parts as may be found desirable. It will thus be observed I have made or provided la thermos bottle almost entirely of glass. In fact, it may be made entirely of glass, but for obvious reasons, I prefer to provide these bottles with a base 14 by means of which the same may be held in an' upright position, instead of trying to make the base portion 5 of the bottle flat to provide a base upon which the bottle may be stood. In this construction the entire top and mouth of the bottle may be kept absolutely clean. There zare no cracks, recesses or spaces which inaybecome filled or which will retain any accumulations of' foreign matter. The entire bottle may be washed and kept clean with a minimum amount of .attention and care.

vacuum bottle there is a circumferential,

space between the neck of the outer glass casing and the metal cover and frequently, during the filling operation, some of the liquid passes therein which when the liquid is being dispensed, niingles .undesirably with the liquid from the inner container. In my improved vacuum bottle there is vno such corresponding circumferential space or passage so that said undesirable min- "gling of the liquid is avoided.y v

It willalso be noted that inasmuch as the whole or substantially the whole of the exterior of my improved receptacle is of glass it may be kept clean muhjmore easily than those forms of .receptacles having metal covers.

' While I have herein shown and described with someparticularity certain embodiments of my invention, I do not thereby desire or intend to limit myself specifically thereto, as suitable changes and modifications may be made in the details of construction and arrangement of the various parts without departing from the spirit and scope of the invention as defined in the appended claims.

Having thus described my invention, what l claim and desire to protect by Letters Pattent is: f
